About the DebugWireProgrammerSchield PCB

DebugWireProgrammerSchield is an open source AVR/Arduino PCB design by joustava, published on GitHub. It is a 2-layer board measuring 57.7 × 20.1 mm, with 16 components from 13 distinct parts.

Its main chip is the ATtiny85, from the AVR/Arduino family. By type, the board carries 5 resistors, 3 connectors, 2 transistors, 2 diodes, 1 IC and 1 jumper.

It belongs with the usb & debug tools and dev boards & breakouts designs in this gallery.

From the project

DebugWire based Debugger/Programmer Shield for Arduino Nano based on https://github.com/wholder/DebugWireDebuggerProgrammer

Once assembled, put the shield on top of a Arduino Nano (assuming you have connectors soldered on the front). Then flash the Arduino Nano with the DebugWireDebuggerProgrammer sketch.

It is now possible to either put a Attiny85 in the socket found on the shield, or to connect to your project by means of a In Circuit Serial Programming (ICSP) connector.

If you use PlatformIO you can use the supplied config and src to upload a simple firmware that flashes the IND. LED on the shield.

DebugWireProgrammerSchield: common questions

What microcontroller does the DebugWireProgrammerSchield use?

The DebugWireProgrammerSchield is built around the ATtiny85, from the AVR/Arduino family.

How big is the DebugWireProgrammerSchield PCB?

The DebugWireProgrammerSchield measures 57.7 × 20.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the DebugWireProgrammerSchield?

16 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the DebugWireProgrammerSchield design files?

From the joustava/DebugWireProgrammerSchield repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the DebugWireProgrammerSchield design in my own project?

The repository has no license, so all rights stay with joustava. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the DebugWireProgrammerSchield without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
